Avoiding Medicare Denials for Lab Tests

Imagine how frustrating it is for a patient to be billed full cost by the laboratory for a test that was previously covered in the past.  It generates the unecessary extra work of dealing with phone calls from unhappy patients or balance billing patients for “uncovered” tests
